The Glastron DS 205 2008 is a modified-V design and the Glastron GS 209 2012 is a deep-V design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

On paper these two are close siblings in the size department - Glastron DS 205 2008 at 20,0 ft versus Glastron GS 209 2012 at 20,2 ft. At 2 930 lbs and 2 832 lbs respectively, both sit in a similar weight class - either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

Both boats share a closely matched power ceiling - 270 hp for the Glastron DS 205 2008 and 270 hp for the Glastron GS 209 2012. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Glastron DS 205 2008 carries 50 gallons versus 45 gallons in the Glastron GS 209 2012. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Glastron GS 209 2012 is rated for 8 passengers, while the Glastron DS 205 2008 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Glastron GS 209 2012 could be the deciding factor.
